  1. 1. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Gustav Larsson; [2023]
    Keywords : organic solar cells; polymer; morphology; film; AFM;

    Abstract : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

  3. 2. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Dominika Kiesling; [2023]
    Keywords : oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Abstract : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.

  4. 3. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

    Author : Khalil Daloul; [2023]
    Keywords : Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Abstract : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. READ MORE

  5. 4. Holocene vegetation change and its correlates in fennoscandia

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Raphaela Infanger; [2022-10-21]
    Keywords : Fennoscandia; Holocene; human impact; climate impact; vegetation change; fossil pollen;

    Abstract : Climatic and anthropogenic legacy has differently impacted vegetation and its community composition. To determine the extent and origin of changes across Fennoscandia, representative regions were defined that entailed sufficient spatial and temporal data. READ MORE

  6. 5. Insight into cosmetology, emulsions and product development in a Fast-moving consumer good company through the scaling up of a salicylic acid cleanser

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik
